Well, your opinion, as wrong as it is, is always appreciated.
Unless you're working with video, it is unlikely you will see much noticeable (as in real-world, not lab tests) difference between a fragmented and defragmented drive. Also, if you're noticing performance degradation due to page-ins (not page-outs as they are harmless) on a machine with 3GB of memory, you need to seriously rethink your workflow.
Oh, and if you're running Vista, you never need to defrag.
